Here is one I just can't seem to find a conversation for. Ladies, have you ever had a guy/girl rub your cervix? Either by a big dick or a big toy. NOTE: I said "rub" not "hit". If your cervix is hit you have every right to kick the shit out of them till you stop hurting.
I've found quite a lot shows up if you punch "cervix" into the search tool Plus there's this thread, which dealt with the topic anatomically, analytically, and anecdotally: http://www.lpsg.org/72217-spot-why-some-women-like.html Check cbrmale's links for some interesting, if clinical, data.
There's actually LOTS on this subject here. A simple advanced search using the key word "cervix" brings these threads up (and these are but a few of many): http://www.lpsg.org/125525-having-cervix-bumped-during-sex.html http://www.lpsg.org/48303-hitting-the-cervix.html http://www.lpsg.org/37135-hitting-her-cervix.html http://www.lpsg.org/39074-cervix.html http://www.lpsg.org/38458-cervix-levels-of-sensitivity.html http://www.lpsg.org/33796-cervix-hitting-questions.html Only when I'm not aroused enough or in certain positions. It does not feel good.
